BS EN IEC 61897:2020

This standard BS EN IEC 61897:2020 Overhead lines. Requirements and tests for Aeolian vibration dampers is classified in these ICS categories:

• 29.240.20 Power transmission and distribution lines

IEC 61897:2020 is available as IEC 61897:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61897:2020 applies to aeolian vibration dampers intended for single conductors or earth wires or conductor bundles where dampers are directly attached to each subconductor. The purchaser may adopt part(s) of this document when specifying requirements for cables different from those mentioned above (e.g. optical ground wires (OPGW), all dielectric self-supporting optical cables (ADSS)). In some cases, test procedures and test values are left to agreement between the purchaser and the supplier and are stated in the procurement contract. Annex A lists the minimum technical details to be agreed between purchaser and supplier. Throughout this document, the word “conductor” is used when the test applies to dampers for conductors or earth wires. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Consider, in addition to Stockbridge type aeolian vibration dampers, also spiral aeolian vibration dampers and elastomeric aeolian vibration dampers. b) Consider the application of dampers on high temperature conductors, specifying additional high temperature tests in clamp slip tests. c) Simplify the procedure of the damper effectiveness evaluation. d) Introduce test at low temperature on fastener components such as break away bolts and conical spring washers. e) Include figures showing the test arrangements for the main mechanical tests.
